Application tiled December 20, 1909. Serial No. 534,141.

To all whom 'it may concern 'Be it known that I, AnToNiNo Cionrr, a subject of the King of Italy, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful ,Improvements in Syringes,

of which the following 1s a specification.

This invention relates to s rinfes or more` l D i particularly, to cannula: or similar instruments used in the treatment of internal, diseased tissues, or, still more particularly, to

. the class of such said instruments as employ a current of electricity to cause a decomposition or an electrification of the fluids in* jected for the respective treatments.

The object of the present invention herein is to providea device that has a circulating passage therethrough, electrodes in such circulating-passage, a dam or guard to close the mouth of the cavity to be treated and to limit the entrance of the device therein and a multiple of radially-distending arms or dilators pivotally-held under tension on Ithe stock or body portion of the device and having'. means to positively operate them for securing the desired expanslon or spreading of the internal tissue that is to be placed under electrolytic treatment, resulting in the destruction or extermination of all germs and disease-producingbacteria.

. Inthe accompanying sheet of drawings l show several forms ol the device that for all practical purposes may both be considered as coming within the scope of the claims that immediately follow the description of the several views of said sheet of drawings.

'In thedrawings, Figure 1 is an axial section partly -in elevation, of one torm ot my device ;Fig. 2, an elevation of the device seen in Fig. 1, but with the inlet and outlet elastic-tube attachments broken ot close to the shank' or head end of the syringe; Fig. 3, a fragmentary section showing the nozzle, the guard' ordam and one of the expanding arms or spreaders, the latter being in elevation along one side edge Atheroot;V

Fig. 4, a transverse 'section ta on on the dotted-line a, a, of Fig. 1, showing the body portion of the nozzle, the circulating-pas the eccentricl notches or recesses 1n theouter tace ot said body portion ofthe nozzle, the sleeve or llange portion of the guard or dam and the pivotal end of each of the spreaders or dilators that contains the inner projections or inclined lugs that engage the said eccentric notches or recesses in said body port-ion of the nozzle; Fig. 5, a view similar to Fig. 1, but showing the device partly in section and partly in elevation and with another form of spring-tension on the dilators or spreaders and, also, showing the manner in which the device is capable of lengthwise adjustment on the nozzle within the guard-sleeve or flange instead of the rotative adjustment of said nozzle within the guard-sleeve seen in the previous four views; and Fig. 6, a plan view of the device seen in Fig. 2 but with the electric plug inserted and without the elastictube inlet and outlet nipple attachments.

In l describing the several views of the drawings, I shall first take upall but Fig. 5 and then follow with its description.

1 indicates the barrel or body portion of the distributing-nozzle, having ahead or shank2 at its upper end and being made somewhat tapering toward its fore end. A circumferential shoulder 3 is provided on the nozzle against which the guard or dam 4 engages, such guard or dam being placed on the nozzle from its said fore end.

5 is a. sleeve or hub project-ing from the dam or guard 4 toward the said fore end o the nozzle, a circumferential groove 6 being made in said sleeve or hub near the guard.

7 and 8 indicate vertical passages leading from the top of the shank or head 2 to the Y said fore end of the nozzle, a triple vertical series of perforations `9 being made at either side the nozzle and leading to the said passages 7 and 8, as best seen in Fig. 1.

10 indicates a metal plate or bar, preferably platinum, suitably held within the lower end of each of the passages 7 and 8. These plates are made arc-shape in crosssection and are preferably toothed or serrated or slitted along their opposite edges, as shown at 11 in Fig. 1 and they are buried or placed sulliciently deep in the lower ends of the passages 7 and 8 to avoid direct eontact with the tissue under treatment.

12 and 13 indicateinternal wires or conductors leading from sockets 14 and 15 made in the shank or head 2, as best seen in Figs. 1 and 2, and connecting said sockets w1th the-upper ends of the barsor plates 9, the latter forming'suitable electrodes when a current-supply is'att'orded through the plug 16 and its connecting-wires 17, the .latter lie leading to any suitable source of electriccurrent. l

18 indicates an inlet nozzle-attachmcnt whose lower, tapering end engages the upper end of the inlet-passage 7 and whose j ment 18 for regulating or shutting oft the hub 5 so as to sustain the ring in place in the liuid passing through the device into the cavity.

20 indicates an outlet nozzle-attachment whose lower, tapering end engages the upper end of the outlet-passage 8 and whose' outer end is also adapted to be engaged by a rubber hose or the like (not shown) similar to the hose used on the inlet-nozzle 18 and forming a drain-tube for the device.

21 indicates each of a multiple of four arms Whose upper ends are rounded, as shown at 22 1n Fig. 3, forprovidmg a sultable bearing on which each one of the arms 21 pivot in a recess 23 made in the sleeve or hub 5 just beneath the guard or dam 4.

24 indicates a spring-ring whose opposite ends are slightly spaced apart, as shown in Fig. 2, and provided for engagement with the groove 6, one end of such ring being preferably bent or hooked inwardly to engage4 a shallow socket or opening in the groove and prevent its accidental turning or disengagement. Said ring 24 also engages grooves made in the upper ends of' the arms 2l `and is adapted to pla-ce said arms under tension in a closed position along the main nozzle 1. The.lower or outer ends of the arms y21 are preferably flared inwardly beginning at a point just below t-helower end 'of the hub 5, as best seen in Fig. 1, thus providing for the corresponding taper'in the lowel` or main portion of the nozzle 1 and facilitating the entrance of the device into position for use. In Figs. 1 and 2, I show the arms 21 as extending almost the ent-ire length of the nozzle 1 down to its fore end and, also, several of the arms as extending a lesser distance downwardly toward the said fore end of the nozzle, the object of such difference between the lengths of such arms being for the purpose oi using the shorter arms in.avoidingcontact with any protruding parts that might be injured by such contact. This feature is quite an important 4one of my invention herein, al though not necessarily an essential one, for the reason that the arms might all bc made the same length so as to extend down to the said fore end or t-ipV of the nozzle. The preferred form of using my distendl ing-arms or dilators, after the nozzle has been'duly inserted in the cavity under treatment, is shown in said lirst four views of the drawings, in which the guard 4, with its hub 5 are rotated the length of the horizontal slot 25 made in the said hub 5, as best seen in Fig. 2, a screw-stop 26 being used in said slot 25 to limit the said rotary movement of the hub and guard. iOn the inner face of the upper end of each otl the arms 21, I provide an inwardly-projecting lug 27 having an inclined inner face 28 that engages the eccentric-bottom of the notch 29 made in the body portion 1 of the nozzle. In Fig. 4 is best shown the horizontal series of the eccentric-bottomed notches 28 and inclined lugs 27 that engage same, the said lugs being engaged atthe innermost ends of the several notches 29, whichis the position assumed when the ar1ns21 are in their normal positions Jfor the entrance and withdrawal of the device'to and from use.

In lthe operation of the device, after the same has been placed in the cavity tor a treatment, the arms 21 are readily spread outward by simply turning the head o1" shank 2 with one hand while holding the guard or dam 4 with the other hand, whereby the Walls of the cavity are stretched so as to receive the full treatment overv they entire surface thereof, such treatment including the use of a medicated liquid that has been electrified by the current passing from the electrodes 10 and thereby setting up an electrolytic action calculated to eHectually destroy the disease germs or bacteria causing the' ailments Within the cavity. The device can be used for flushing with other than 1nedicated fluids and Without the use ofthe electric-current if desired, which is quite obvious and will need no detail description herein.

In the devicel shown in Fig. 5, the guard or dam 4 and its hub or sleeve 5 do not rotate around the shouldered body portion l of the nozzle, but they are adapted to slide.

lengthwise along said body portion 1 teward the fore end of the latter and thereby cause the dilator-arms 21 to spread VHontwardly. A vertical` slot 30 is made in Gthe hub 5 and a screw 31 is used in said slot to limit the lengthwise-movement of the said hub and the accompanying guard or dam along the nozzle 1, such limiting movement being determined bythe extent 0'1"' desired spread or expansion of the dilators 21. stead of the eccentric-bottomed notches 29, used in the device shown in the previouslydescribed views, vertical notches having inclined bottoms 82 are used and the lugs 27 on the backs of the upper ends of the arms 21 are inclined vertically to coincide with said inclined bottoms 32, the latter causing the arms 21 to spread outwardly on their pivots 22 when the guard or dam 4 slides `lengthwise toward the fore end of' the no zle.- 'A-vertical plate spring or elasti arm 3317s Vused to exert the desired' tension on mog-see 3 each ofthe arms 21, instead of the springheld b the guard or dam while the shankend o the nozzle is drawn outwardly to spread the arms 21.

It will be observed that a `distinct advantage is gained by having the several spreader-arms or dilators detachably-l hinged in place so that either one or all o them can be'removed for use in -full number or in a less number to suit the' ailment under treatment. The spring-ring form of tension for such spreader-arms and, also,

rthe springgarm form of tension are both adapted toY sustain the said spreader-arms in closed lposition over the nozzle and to permit either one yof such spreader-arms to be readily removed and replaced. This readily detachable forni oi mounting the spreaderarms in the device also facilitates the very ready cleaning thereof which is a very necessary yelement in its use for the very serious reason that disease germs lurk in parts or joints that are rigid or that cannot be readily separated. Besides, said detachable-mounting of the spreader-arms enables the entire removal thereof when it is desired to use'the nozzle as an ordinary irrigator or thisher that frequently occurs.

The serrated or toothed edges of the electrodes are especially adapted to present a greater contacting surface than .would a plain electrode and, also, to deliver the electric current into many points of contact with the fluid used, thus resultin in a better impregnation or saturation o said current in` producing the desired electrolysis for killing and destroying the disease germs.

In order that the spreader-arms or dilators 2l may not materially interfere with the Contact of the treatments when the device is in operating position in the cavity, I prefer to construct each spreader-arm or dilater with a series of perfor-ations or openings 2l, such as is shown in the series oi perforalions in the spreader-arm (to the left) in Fig. 2. Otherwise, the broad solid surface oit' the spreader-arms would interfere to a considerable extent while under dilating action, unless the device is returned to normal position Within the cavity and then turned at least the breadth of the respective spreader-arms within said cavity.

I claim 1. In a syringe or cannula used for internal medicinal treatments, a nozzle having inlet and outlet passages therein, perforations at the fore end ot' said nozzle leading to said inlet and outlet passages, a guard or dam having .a hub or sleeve portion engaging a shouldered portion of said nozzle adjacent its outer or shank end, a plurality of arms or dilators having hinged connection yunder tension with the said hub or sleeve of the dam, means comprising lugs on the inner faces of the upper lends of said arms or dilators having inclined faces, notches or recesses in the portion 4ot' the body of said nozzle that lies adjacent vto said inclined lugs and having inclined `bottoms adapted elined faces of said lugs and means for supplying and draining the said respective passages in said nozzle.
